It doesn’t take much to kick start the rumor mill again. After a clear absense of chatter over the past two weeks or so, Sandisk (SNDK, news, chart, volatility) is up 77 cents to $16.69 amid renewed takeover talk Monday. Samsung is once again being mentioned. No reaction in the options market yet. Implied volaitity in Sandisk remains elevated, however. In the November 17 calls, for example, implied vols are up to 176 percent, up from 160 last week. SNDK earnings are due out after the close of trading Thursday.
