Partial of my PhD thesis are lots of simulations on this type of technique and validations with data on T+1, T+2, .....After graduation, and I was so confident on myself since all validation results were beautiful (纸上谈兵 always looks nice, haha), I put the real $$ to practice my strategy.......I paid 6 digits of tax in the "bubble year" due to short term gains; but (don't you hate the word, but, ) almost lost my shirt in the losing year.
Finally I gave up the game and focused on kids (better or worse investment? My older one is going to cost me $65k this year and I think the return to me is -100%, Heehee). In past 10+ years, I am still doing options but 95%+ covered and only 5% or less naked. Also, every time when I achieve profit goal (defined by myself -- 25% over the base), I took $$ out to buy rental.
小散什么也不是 - Having been in financial market for so many years, I strongly agree with you!
So many times I hear that so called "1% a day" (那谁谁, don't 扔砖头), I cross my fingers. Now I don't accept any clients request for "beating the market". I am so happy doing great job on risk management.......
I guess the home made wine is too good tonight :>) . Again, thank you so much, Mr 老瞎!!! Good night!
