Where can I find 3-5 year historical data showing average or leading financial ratios by industry. For example, in industries like wireless, telecom,or biotech.
The ratios I'm referring to are these metrics:
- P/E Ratio
- Market to book Ratio
- Quick Ratio
- Current Ratio
- Debt to Equity
- Return on Assets
- Return on Equity
- Inventory Turnover
- Asset Turnover
I can usually find them for individual firms or calculate them on the 10-K statements; however, I have not found a reliable source on the web to compare to industry averages.
I read through this post but it seems like it only has current data:
Are there pay services perhaps?
