Insiders In Lumos Diagnostics Holdings Left Out From 11% Price Rise After Disposing Stock

Lumos Diagnostics Holdings Limited's (ASX:LDX) stock rose 11% last week, but insiders who sold US$428k worth of stock over the last year are probably in a more advantageous position. Holding on to stock would have meant their investment would be worth less now than it was at the time of sale. Thus selling at an average price of US$0.40, which is higher than the current price, may have been the best decision.

Although we don't think shareholders should simply follow insider transactions, we would consider it foolish to ignore insider transactions altogether.

The Last 12 Months Of Insider Transactions At Lumos Diagnostics Holdings

The insider, David Bottomley, made the biggest insider sale in the last 12 months. That single transaction was for AU$176k worth of shares at a price of AU$0.39 each. While we don't usually like to see insider selling, it's more concerning if the sales take place at a lower price. The silver lining is that this sell-down took place above the latest price (AU$0.20). So it is hard to draw any strong conclusion from it.

Happily, we note that in the last year insiders paid AU$227k for 4.63m shares. But insiders sold 1.08m shares worth AU$428k. Over the last year we saw more insider selling of Lumos Diagnostics Holdings shares, than buying. The chart below shows insider transactions (by companies and individuals) over the last year.
