High tech start-ups are being urged to take advantage of soaring share valuations to raise fresh funds. Jeffrey Chambers, a managing director at TA Associates, advised an audience of high growth companies at an American Electronics Association forum to: jump now, definitely – I do think this is an unbelievable public market. Trouble is, the advice was coming from someone who stands to earn substantial fees by bringing such companies to market. Companies that need the cash now have little alternative but to float if they are in a state to do so, but the market tends to be very unforgiving to companies that ride the last upsurge of a dying bull market once the market does turn.
