Here’s a list of Tuesday’s penny stocks that traded on unusually high volume. Some of them did so with little to no explanation. Since clearly ’somebody knows something’ though, these penny stock tickers are probably worth exploring a little further, as they may be great trading candidates - volume often precedes big moves.

Oh, and just to clarify our use of the word suspicious when we write this column, it’s not necessarily a connotation of impropriety or bearishness…. it’s just meant to be a subtle hint of interesting activity.

Cellynx Group Inc. (CYNX)

Yesterday wasn’t the only day we’ve seen huge volume in Cellynx shares, but it’s the first time we’ve seen it like this since late May. The stock’s been rising the whole time though.

CYNX is an interesting bird…. lots of news (it seems), but not a lot of substance in terms of performance and results.

Technically speaking, the high volume gain from Tuesday almost looks like a blowoff top, as it occurred well after an uptrend had been in place. In that regard, CYNX may be a better short candidate - the high volume day could just be a pivot. Better to find out what’s going on first though.

Raptor Pharmaceuticals Corp. (RPTP)

We’ve actually seen a strong volume increase over the last five days for Raptor, all of it bullish.

From a short-term view it looks like this penny stock’s over-extended. Longer term though (two years or more) we can see the recent rally from 17 cents to 40 cents still doesn’t even come close to putting these shares back where they were. Could the recent volume increase be the beginning of a recovery move?

The company’s certainly got more going on now than they did before April….two drug-related patents were approved, they began Phase IIb testing of Cysteamine, and have started to collaborate with Roche to develop a drug delivery that crosses the blood/brain barrier.

EnDevCo Inc. (EDVC)

We actually put EnDevCo on our watchlist about a month ago, based on the stock’s rise on high volume in late May. The rally - and the volume - petered out though, so we lost interest….until yesterday. In one shot, EDVC shares are back up towards recent highs, and they got there on the highest volume we’ve seen since February.

So what gives? That’s the odd part - no news at all. Not even a rumor. Someone’s buying though (obviously).

We’re not sure those coat-tails are ready to be ridden yet, but it’s worth keeping an eye on.

OMNOVA Solutions Inc. (OMN)

It wasn’t so much the volume yesterday, but rather the strong move that seemingly came on dwindling volume… quite a surprise.

Yesterday’s buyers did the bulls a favor though. Resistance had been forming between $2.75 and $2.83. Higher lows coupled with mostly-flat resistance mean the formation of a pennant shape, which was broken - bullishly - with the move to $3.05.

The jury’s still out on whether or not the breakout will take flight, but it’s a decent start.
