现在是2025年了，操盘的又升级了。21年以前，都是散户做多，资金费随便吃，仓位随便开，我基本都5x杠杆玩山寨。22年的时候，散户被割晕了，开始学会做空了，主力就玩小币拉升，引诱散户做空，然后一直拉现货。负溢价你受不了。现在25年了，散户也知道小币不能做空，主力找不到对手盘了，就开始搞套利的了。之前pumpbtc应该是有傻大户被爆了几千万刀，最高点3分钟翻倍，然后1分钟持仓掉了4000万刀，典型的套利被爆，主力自动adl。还有hype上xpl也是操纵爆套利的，还有昨晚的bybit的seraph。我也玩小币套利，但是我爆仓价基本都是×100倍。也就是一天拉10倍我都游刃有余。对于小资金还好，不对劲直接砍仓就行了。对于大资金来说，最麻烦的是，你砍不了，别人就是爆你的。比方说我2000万刀保证金，开一个小币套利100万刀，爆仓价看似20倍，但是现在动不动一天拉10倍，这时候你仓位就是1000万刀，你根本不可能减仓的，一定会加速，主力就是盯着爆你去的。 ...

Core Viewpoint - The article emphasizes the importance of accurately estimating one's own winning probabilities and odds in investment decisions, highlighting the risks of overconfidence and the potential for significant losses when using the Kelly Criterion improperly [1][2][3]. Group 1: Kelly Criterion and Overconfidence - The Kelly Criterion is a strategy that helps prevent total loss by advising against betting more than a calculated limit based on winning probabilities [1][3]. - Historical data shows that individuals tend to overestimate their winning probabilities, leading to potentially disastrous investment decisions [2][3]. - The article presents statistical findings indicating that as perceived winning probabilities increase, the actual success rates do not correspondingly rise, often resulting in over-leveraging [2]. Group 2: Risk Management and Investment Strategy - It is crucial to avoid full allocation to a single asset, as this exposes investors to excessive risk and potential catastrophic losses due to unforeseen events [4][12]. - Diversification is highlighted as a fundamental principle in risk management, with the understanding that not all investments will perform well simultaneously [5][12]. - The article suggests that using a fraction of the Kelly Criterion (such as half or a quarter) can mitigate risks associated with overconfidence and market volatility [3][11]. Group 3: Practical Investment Insights - The article discusses the challenges of accurately determining the parameters needed for the Kelly Criterion, such as winning probabilities and odds, in real-world scenarios [11][12]. - It emphasizes the need for a multi-strategy approach in investing, combining high-conviction bets with diversified positions to balance risk and reward [12]. - The importance of maintaining liquidity and having additional capital available for potential market corrections is also noted, as it allows for more flexible investment strategies [4][12].

Core Viewpoint - Leverage is not a shortcut to wealth but a double-edged sword that amplifies both risks and returns, often leading to significant losses in volatile markets [7][8]. Group 1: The Nature of Leverage - Leverage itself does not create value and is not a low-risk, high-return arbitrage tool [8]. - Leveraged ETFs experience "volatility drag," which erodes returns over time, especially in fluctuating markets [9][28]. - The asymmetry of gains and losses is exacerbated by leverage, making it more challenging to recover from losses [12][17]. Group 2: Risks of Leveraged ETFs - A 3x leveraged ETF can theoretically become worthless if the underlying index drops more than 33.33% in a single day [14]. - The concept of "fixed leverage trap" indicates that after a loss, the base for future leverage is reduced, complicating recovery [17]. - High management fees and tracking errors in leveraged ETFs further diminish returns, akin to physical energy losses [21]. Group 3: Historical Performance and Market Conditions - The 3x leveraged semiconductor ETF (SOXL) has shown impressive annualized returns of over 30% in certain periods, outperforming broader indices like NASDAQ and S&P 500 [23][40]. - However, the extreme volatility and significant drawdowns, such as in 2022, highlight the risks associated with leveraged products [26][40]. - The timing of market conditions is crucial for leveraged investments, making long-term holding risky [27][41]. Group 4: Guidelines for Ordinary Investors - Leverage amplifies both risk and reward, making it essential for investors to approach it with caution [47]. - The long-term viability of investments should focus on value creation rather than merely leveraging returns [53]. - Ordinary investors are advised to avoid heavy leverage and to prioritize survival and long-term investment strategies over short-term gains [55].

Core Viewpoint - The article presents ten golden rules for survival in the stock market, emphasizing the importance of risk management, independent thinking, and long-term investment strategies [3][4][5][6]. Group 1: Investment Strategies - Avoid using leverage as it amplifies both gains and risks, leading to potential losses [3]. - Focus on understanding industry logic and long-term value rather than relying solely on intelligence or K-line charts [3][4]. - Stay away from penny stocks and companies with poor financial health, as they are likely to face significant downturns [3][4]. Group 2: Market Behavior - Independent thinking is crucial; following market trends or "hot stocks" often leads to losses [4]. - The stock market is likened to gambling, where long-term value investing is seen as a more favorable bet compared to short-term speculation [5][6]. - Recognize that even high-quality stocks can decline in value during bear markets, thus investors should buy low and hold rather than chase high prices [5][6]. Group 3: Investment Timing and Valuation - Emphasize the importance of understanding valuation, market sentiment, and the potential for price appreciation when making investment decisions [5][6]. - The article suggests that while predicting market timing is challenging, focusing on the potential for price movement (space) is more feasible than trying to predict speed or timing [6].

Core Concept Analysis - Stock market margin trading consists of two related but opposite trading methods: margin financing and securities lending. Margin financing involves investors borrowing funds to buy specific stocks, using their own funds or securities as collateral, while securities lending involves borrowing stocks to sell and repurchasing them later at a lower price for profit. Both methods incur interest and are limited to designated stocks [1]. Key Operational Differences - Margin financing is a bullish strategy where investors expect stock prices to rise, borrowing funds to buy stocks and selling them later for profit. Conversely, securities lending is a bearish strategy where investors expect stock prices to fall, borrowing stocks to sell and repurchasing them at a lower price for profit. This creates a two-way trading mechanism [2]. Characteristics of Target Stocks - The stocks eligible for margin trading are determined by exchanges, typically including large-cap, liquid, and stable-performing stocks, such as those in the CSI 300 and CSI 500 indices. The list of eligible stocks is periodically adjusted, and stocks removed from the list cannot be traded through margin financing or securities lending [3]. Margin Requirements - Participants in margin trading must pay a margin, which can be cash or eligible securities. The margin ratio for both margin financing and securities lending is usually no less than 50%. For instance, with 1 million yuan of personal funds, an investor can borrow up to 1 million yuan under a 50% margin ratio, with specific ratios adjusted by institutions based on market conditions [4]. Interest and Fee Characteristics - The interest on margin financing and the fees for securities lending are calculated based on the actual number of days used, with annualized rates generally ranging from 6% to 8%. The financing interest is based on the amount borrowed, while the securities lending fee is based on the market value of the borrowed stocks, which must be accounted for in terms of cost and expected returns [7]. Risk Control Mechanisms - A maintenance margin ratio is enforced, calculated as (own funds + market value of held securities) ÷ (financing liabilities + securities lending liabilities). The warning line is typically set at 130%, and the liquidation line at 120%. If the ratio falls below the warning line, additional margin must be provided or positions reduced; if it falls below the liquidation line without timely remedy, institutions have the right to liquidate positions to ensure fund safety [8]. Characteristics of Applicable Groups - Margin trading is more suitable for investors with certain experience and a higher risk tolerance. Margin financing is appropriate for those predicting stock price increases, while securities lending suits those anticipating price declines. Both require investors to accurately grasp market trends and manage risks associated with price fluctuations, making them unsuitable for novice investors or those with conservative risk preferences [9]. Differences from Ordinary Trading - Ordinary trading allows only for buying before selling, with profits dependent on rising stock prices. Margin trading introduces a short-selling mechanism (securities lending), enabling profits in declining markets. Additionally, margin trading incorporates leverage, amplifying both potential returns and risks, while ordinary trading lacks such requirements, making it simpler and more direct [10].
