UBS has updated its Tech 10 portfolio by adding semi-packaging/assembly equipment provider ASM Technologies as a least preferred stock. Tech 10 is a market-neutral basket of the five most and five least preferred global equities.

Since its inception on Dec. 9, 2008, the Tech 10 Portfolio has held 103 stocks, including 44 most preferred and 59 least preferred. Of the 44 most preferred, 26 advanced and 18 declined while on the list. Of the 59 least preferred, 23 moved lower (added value) and 36 moved higher (lost value) while on the list.

The Tech 10 portfolio is up 16.0 percent year-to-date, versus a 3.1 percent decline in the HFRI Equity Market Neutral Index. Since its inception, the Tech 10 is up 67.4 percent versus a 5.9 percent HFRIEMN decline.

We prefer a mix of firms that can benefit from troughing cycle trends (KLA, Micron), secular growth in security/mobility (Check Point, Qualcomm), and strength in emerging/IT (Synnex) over names with less compelling risk/reward, increased competition, and fewer near-term catalysts (ASMPT, Citrix, CSC, Gemalto, Nvidia), analyst Nikos Theodosopoulos wrote in a note to clients.
