Free investment tools
Value a company, test a portfolio shock, or calculate what has to happen for an investment to work.
DCF Model
Estimate value per share. Change operating assumptions, test sensitivities and download the formula-based Excel model.
Example
| r \ g | 6% | 8% | 10% |
|---|---|---|---|
| 8% | $75.13 | $82.09 | $89.56 |
| 9% | $62.94 | $68.72 | $74.92 |
| 10% | $54.01 | $58.93 | $64.20 |
Reverse DCF
Calculate the cash-flow growth needed to support a valuation.
Example
Required FCFF growth
13.5%
$20B EV, $800M FCFF, 9% rate, 5 years
Portfolio Stress Test
Apply a hypothetical shock and see which holdings contribute most to the loss.
Example
| SPY | -$10,000 |
| TLT | $1,500 |
| XLE | -$2,000 |
| Portfolio | -10.5% |
