PE of 4024 Feb 2016 10:57
With a PE of 40 the market is expecting a lot from ISL, so their shares look expensive. The share price is without doubt very bullish and their last trading statement is very positive.
Downside: Are they setting themselves up for a fall with the words "significantly ahead"? The expected new business is not signed yet so it is always possible that contracts can be delayed or lost. In the IT market, some firms are golden and will race ahead, but the road is littered with many casualties.
