Was this call-buyer just a little too "linked in"?

Dear SEC, what are you doing?

Friday saw an oddly yuuge trading volume suddenly spike in LNKD's August $160 Calls...

As it appears some very 'lucky' trader bought 500 lots (50,000 shares) at $2.26 Friday morning...

Only to be so lucky that Microsoft decided to massively overpay for his underlying stock... And, judging by the dump in implied vol, was selling those exact 500 calls back to the greater fools at $33.89 this morning.

A nice $1.5 million profit or 1300% return over the weekend.

Nice work if you can get it.
