After SanDisk's earnings report, Micron and SanDisk memory stocks have surged again.Practical advice:• When profit margin reaches 100%: Withdraw the principal decisively;• When profit margin exceeds 50%: At least halve the position;• If using 2x long leverage: It is essential to reduce positions and recover the principal now.Warren Buffett said the first rule of investing is: Don't lose money. The second rule: Never forget the first rule. In fact, there is never a shortage of money-making opportunities in the market. Only by having the courage and determination to sell will you always remain at the investment table.  Of course, I am very bullish on memory, so I only sold the principal.I remain bullish on memory for 26-27."
