Anyone know what’s causing the drop?, page-5

yeah. But also with PLX there is lack of liquidity so it can be moved on quite small dollar amounts. For some reason the market doesn't value it as highly as other tech stocks in terms of multiples. They are projecting 500m users in the next few years. That generates a fair bit of user behaviour data that PLX are paid to collect and try interpret for the customer. That is the value, the backend, not making apps.
