Good profit announcements

I have invested in a few technology stocks in the last 4 months.

CT1, WTC, NXT, APT all had great results but strangely 2 plunged and 2 jumped with good profit announcement.

Then SYD, RIO and BHP made good profit announcement but there is no dramatic response.  Same with the big 4 banks.

WES is struggling with its hardware store investment in the UK and its share price went up!

Obviously, it depends on what the fund managers are expecting.  If profit is good but not as good as anticipated, then crash!  However, I am there for the long term.  Usually, bad reports are punished but WES strangely went the other way!

But the star is VLA because of a takeover by MSD so that portfolio has a nice spurt.
