I noticed the very same concerns on the chart. MRVL closed just $.03 above the LOW for the day---not a good sign at all; on 94% MORE than normal daily volume. HIGHER volume on lower prices is a bad indicator
"only positive thing on chart is stock is oversold."
However, a stock can remain "oversold" for a v-e-r-y long time.
There is some support in the $14.80 area---but not much. Regrettably, $14.33 is the low; if earnings AND guidance disappoint, this could be where MRVL may find support.
If earnings AND guidance are above expectations MRVL could test the "double top" of February 21 and April 1st., around $16.
Today's action would suggests that the MRVL smart money is betting lower prices before it goes higher.
