Sometimes it stinks to be a bitcoin play: Hey, if you want to ride the bitcoin wave as an investor you have to be prepared for randomly getting your face punched in. Case in point are those Johnny- come-latelies who bought payment tech company Square (SQ) - Get Report after it enabled buying and selling of bitcoin in its Cash app. Shares plopped 5% on Wednesday as Fed Chair Janet Yellen said bitcoin is "highly speculative." What, you thought she was going to trash the U.S. dollar? Come on people. Anyhow, Square's stock is now below its 50-day moving average. Memo to Square executives: This month would be a good time to explain to analysts and investors (again) that Square is way more than a bitcoin play. Hit those phones, Jack Dorsey.

There are two ways to look at this one: Scrolling around Twitter last night I came across a plug for Microsoft (MSFT) - Get Report CEO Satya Nadella appearing on the Daily Show. Obviously I had to watch this -- it's not often the CEO of a publicly traded tech giant pops out-of-the-blue onto the set of a comedy show. First instinct is to say that seeing his stock spike almost 40% this year Nadella is starting to relax a little bit by appearing on TV. At that point, maybe investors should be hitting the sell button come the open on Thursday. But the interview turned out to be quite the contrary, a reminder on WHY Microsoft's stock still has a promising longer-term outlook under Nadella's leadership. Nadella has managed to not only reinvent Microsoft, but to also humanize it for Wall Street and the broader public. Microsoft was once viewed as a villain but it's now seen as a giant friendly startup changing the world (not saying it IS that, just the perception). A good deal of that perception change is being fueled by Nadella and with a ton of cash on hand and a strong innovation pipeline (see Xbox One), investors should stay optimistic on Microsoft.

What concerns me about the Disney/Fox deal: Disney (DIS) - Get Reporthas just spent $52.4 billion in stock to buy most of Twenty-First Century Fox (FOXA) - Get Report . This deal won't come cheap for legacy builder Bob Iger. Maybe this is the old stock analyst in me, but is anyone considering how this deal will alter Disney's capital structure? Sure, on the surface Disney will be God in Hollywood as it builds upon its studio empire. On paper, acquiring these assets is sexy as hell. But Disney's leverage may approach -- or be more than -- 70% of shareholder's equity after this deal. Interest expense is going to balloon (it has been on an uptrend) during a time of cord-cutting and when investment in Disney's parks operations is needed. You just wait for the notes from the credit ratings agencies after this deal ...
