Specifically, it combines the operations of 'rsp' (regular fixed investment) and 'sell at high profit' (selling when the profit is high).
Advantages:
1. Diversify risk.By making regular weekly rsp, you avoid the risk of investing a large amount of money at market highs all at once, and at market lows, you can get lower prices, thus smoothing out the cost.
2. Locking in profitsWhen the market rises and the returns reach a certain expectation, locking in profits by selling part or all of the fund can avoid the decrease in returns caused by market corrections.
3. Adapt to market fluctuationsThis strategy performs well in volatile markets, buying at low points and selling at high points to profit from fluctuations.
Possible limitations:
1. Difficult to determine "high returns": In actual operation, it may be quite difficult to determine when to sell, as predicting the market's peak is challenging and may result in situations of selling too early or too late.
2. Cost of frequent operations.: The frequency of fund trading may incur certain transaction costs, especially when the market is volatile. Excessive buying and selling can increase costs, thereby affecting overall returns.
3. Not suitable for a one-way upward market.If the market continues to rise for a long time, the effect of regular investment may weaken, as the opportunities for buying at low levels decrease, and the returns will be relatively limited.
Summary:
This strategy may be more effective in volatile markets, as it can profit from fluctuations. However, in trending markets (such as long-term uptrends or downtrends), its effectiveness may be inferior to lump-sum investment or long-term holding...

1. Do not invest in things you do not understand.
2. Do not invest in things you do not believe in.
3. People feel the impact of 'loss' more strongly than 'gain'. Do not be afraid of earning less, be afraid of losing more.
4. Those who encourage you to invest will not foot the bill for your losses.
5. Stay away from excessive confidence and herd mentality. Focus on long-term returns. Do not indulge in short-term gains.
6. The most important thing in investment is being able to sleep well at night. Things that cause anxiety when consumed are often not good.
