ARM Holdings (ARMH) and ASML Holdings (ASML) are retreating, after JP Morgan analyst Mark Moskowitz wrote that a supply glut of tablets may develop this year. The supply of tablets this year could exceed demand by 36%, as projections for sales of iPad competitors may be too high, the analyst warned. Shares of British chip maker ARM Holdings (ARMH) - which receives royalties from tablet sales - could be negatively impacted by a downward shift in sentiment towards the tablet space, he wrote. Shares of ASML Holding - which makes equipment for semiconductor manufacturers - could be hit by reduced equipment spending if the supply glut spreads to products other than non-Apple tablets.
