Underlying Risks in Speculative Biotechs Can't Be Overstated

Originally published Sept. 16 at 9:06 a.m. EDT

I have followed Novavax(NVAX) - Get Report for several years.

After Thursday's market close, the company announced the results of their Phase Three trial for a respiratory-virus drug. NVAX missed its goal, and the shares are trading down by about 80% ($8.40 to $1) in premarket action.

The company had worked on approximately 1,600 patients in its Phase Two Trial (split 50% of subjects on drug, 50% not). Unlike Portola Pharmaceuticals(PTLA) - Get Report , which could stilll potentially file its drug later this year, the NVAX drug showed no difference from the placebo.

So, essentially, the drug didn't work.

This huge percentage decline underscores the risks associated with speculative biotech stocks.

That is why, if you are interested in speculating, a basket should be employed.

Position: None.

Trump Speaks, Bonds Slide

Originally published Sept. 15 at 1:25 p.m. EDT

Bonds have taken a tumble, coincident with Donald Trump's midday speech at the New York Economic Club.

Before his speech, the iShares Barclays 20+ Yr Treas.Bond ETF(TLT) - Get Report was down $0.30. Now it's down $1.05.

The yield on the 10-year U.S. note is up by over three basis ponts to 1.72%, and the long bond is up five basis points to almost 2.50%.

The 2s/10s spread has widened rather sharply -- by nearly five basis points to 98 basis points (a recent high).

Position: Short TLT.

Take Notice: Sentiment Is Shifting

Originally published Sept. 15 at 9:32 a.m. EDT

I don't live or die on investor sentiment changes, but I do pay attention to large shifts.

As I mentioned earlier this week in "Was Friday the Correction's End ... or Just the Beginning? and as The Divine Ms M mentions today, The Bull Market in Complacency has moderated.

Here is CNN's Fear and Greed Index, which has come way down in recent weeks from green (greed) to red (fear).

Again, changing sentiment is not my sine quo non, but it plays a part in my analysis of the investment mosaic, which is importantly skewed toward fundamentals and, to a lesser degree, valuation.

I start the day in market-neutral position.

Position: Short SPY small.

Slicing the Size of My Apple Short

Originally published Sept. 15 at 10:54 a.m. EDT

With Apple(AAPL) - Get Reportmoving right through technical resistance, I have reduced the size of my Apple short from medium to small.

This move represents risk control and doesn't reflect a fundamental change in my view of Apple's profit outlook.

As it is said, discipline often trumps conviction in this game.

I will mostly likely add back to my short position in Apple when I have a sense that the current move is exhausted. So this move should be viewed as tactical rather than fundamental.

Position: Short AAPL small.

Action Alerts PLUS, which Cramer co-manages as a charitable trust, is long AAPL.
