A failed attempt at a terrorist attack in New York and further shakeups at General Electric Co. (GE) - Get General Electric Company (GE) Report  did little to sway markets on Monday, as the S&P 500 and Dow Jones Industrial Average both closed at new records.

The Nasdaq also finished higher. And one of the most talked about Nasdaq stocks was also among the hot stocks of the day, as Elliott Management, the activist hedge fund pushing for Qualcomm Inc. (QCOM) - Get QUALCOMM Incorporated Report  to raise its bid for Dutch chipmaker NXP Semiconductors NV (NXPI) - Get NXP Semiconductors NV Report  , said on Monday it believes the firm is worth $135 a share, "far above" the current $110 a share offer.

The situation is complicated by the fact that Qualcomm is itself in the midst of a $130 billion hostile takeover attack from rival Broadcom Inc. (AVGO) - Get Broadcom Inc. Report  . Broadcom is seeking to oust Qualcomm's entire board and on Monday said that it had filed a pre-merger notification under the Hart-Scott-Rodino antitrust rules.

Elliott isn't the only shareholder not willing to tender its shares at $110 a pop.

"As we have been describing in our bulletins and weekly roundups, our takeaway here is that we find that the $110 tender offer discounts the value of NXPI as well, and Elliott's analysis supports our thesis," wrote Jim Cramer, portfolio manager of the Action Alerts PLUS Charitable Trust, which owns NXPI. Subscribe to AAP to find out what they think is a fair price for NXP and for their thoughts on Broadcom, also a holding in the trust.

Amid the continued strength in the overall markets, that nascent digital currency, Bitcoin, continued its astronomical journey. After Monday's 9.4% increase to $17,150, Bitcoin is up a whopping 1,680% this year.

Not that you missed this - it's pretty hard to ignore - but TheStreet today took a look at how Bitcoin's recent run-up compares with some other historic manias, including the Nasdaq bubble of the late 90s - where Amazon.com Inc. (AMZN) - Get Amazon.com, Inc. Report  rose 1,100% in 1998 alone - as well as the tulip bulb craze of the 1630s, which saw a single flower cost more than a house in 1636 and 1637.
