Read Broadmoor's post - There is a very good reason why they're so cheap.

Just because they're cheap now doesn't mean that they're going to be a good investment, unless you've discovered some BIG news about the company?

According to Wikipedia -

"In July 2008 Taylor Wimpey announced it was experiencing a 'significant downturn' in its major markets[9] and as a result it would close 13 of its 39 regional offices. With a debt of £1.7bn, lenders were also insisting on disposal of Taylor Woodrow Construction after Taylor Wimpey failed to raise £500m in capital.[10] When it was learnt that the Company could not raise new capital share prices plummeted more than 50%."

Even with my limited grasp of the building trade - it's going to take a LOT of houses for for the company to start being a viable proposition surely?
