NEW YORK (TheStreet) -- "Change is inevitable. Growth is optional." - John Maxwell

On Thursday we saw stocks continue to move. A few new ones we've been eyeing really took off from buy levels.

The indices began to move, with strong volume. There was superb action Thursday that we have been looking for and are taking advantage of.

We added more to Baidu (BIDU) - Get Report, Clovis Oncology (CLVS) - Get Report and  Illumina (ILMN) - Get Report Thursday and we're still holding Flextronics (FLEX) - Get Report, Regeneron Pharmaceuticals (REGN) - Get Report and Google (GOOGL) - Get Report, while we started new positions in Amazon (AMZN) - Get Report and Vipshop (VIPS) - Get Report.
Regeneron isn't working great yet but not showing a loss either.

We should be able to hold these stocks for a few days at least, but we are still completing bases, so shorter swing trades are still what I see as the best way to maximize gains in this market.

I'm heavy in stocks now, but that can change quickly (just as I bought them quickly) on any sniff of trouble.

I have no qualms booking gains. The worst that can happen, aside from massive gaps lower, is I get stopped out for smaller gains or cost.

I really don't like having any more positions than this at once, so now it is about watching and managing these positions.

Let's check out the S&P 500 SPDR (SPY) - Get Report index:

SPY broke my 193 most recent buy level Wednesday and has now accelerated higher on increasing volume, which is key. The 196 to 198 areas are now in play. We should rest and consolidate once we hit that area, but I have to see the action at those levels to know how to gauge what happens next.

All in all, a great day and we should see many more of these over the summer.
