WOW - yes indeed...but instead of looking at it on a daily basis like a rookie investor would, let's take a longer term look:
Since you showed up on this board, ISRG has gone UP from ~$260 to $390 and topped out near $600. Titan Medical, a PINK sheet stock with NO products, has gone DOWN from $2.2 to $1.2 and now hovers in the mid pennies (over a 75% DROP).
So, who's really the dog/fool? Calling others "fools" does not negate nor detract from your own obvious investment failures. If we had followed any of your poor advice when you first showed up everyone would be as broke as you are.
