In the NASDAQ bubble of 1999-2000, etc. the NASDAQ was overvalued at 3000, 4000 and over 5000. Did it matter that one didn’t catch the top if they got out at 3000 or 3500, etc? No. Why? Because, more importantly, they dodged the down-draft from 5200 down to 1100.
So, which was most important? To catch the rest of the uptrend ride (whcih no one could do)? Or, to avoid much of the massive bubble/crash, which entailed far more points?
So, I won’t worry about catching the final 1000 to 1500 points of an uptrend because of the risk of a 4,0000 point decline on a 5200 level index. That’s the perspective one should take.
