shut up and go all in long at all time highs then idiot, put your money where your mouth is
You only know if we are at all time highs in HINDSIGHT. Nothing indicates that we are short, so as long as the trend is long you should not go short. You know why?
I personally know 1 person who lost over 10 million$ (yes ten million dollars). In futures S&P.
He sold 210 contracts at 250$ a point at 495 in 1995 (Emini did not exist yet). In 1994 he made more than 1 million profit. When things went wrong he waited till the market retraced. But in 1995 it didn't retrace anymore at all. After lots of margin calls his account got wiped out completely.
He was sure the market would go down. He was right, in 2000, 5 years after he already went short as the top was reached, the market really went down. But at that time the market was THREE times higher ( +- 1500) then the level where he took his shorts.
So, although in 1995 the market was already for years at new all time highs, the most stupid thing to do was go SHORT. In hindsight it is very clear.
Who is the idiot at this moment? The one going LONG? Or the one going
SHORT?
You should always know what to do in in reaction to what the market does. You should never do what you think the market will be doing soon. Pro active is not good.
