This formula (the Gordon growth model), doesn&#x27;t really apply here, cause the g is for perpetual growth. For example, if you plugged in FB&#x27;s current growth rate, it would blow up to something ridiculously large. The rule of thumb is that it should never be larger than GDP (since that company would quickly come to dominate the national economy). Tracking inflation is safe if the company can at least raise prices to match inflation.<p>If you don&#x27;t want to set up a full DCF, the Benjamin Graham formula gives a quick intrinsic value estimate:<p>V = E * (8.5 + 2g) * 1.1,<p>E is earnings (FCF, or a modified form like owner&#x27;s earnings would work also), but here, g is the growth rate for the next 7-10 years.<p>This still wouldn&#x27;t work for TWTR, since negative earnings always give you a negative value, so you would have to project out the next few years until twitter has positive earnings (or positive FCF), then you could use the Graham formula and discount it back to present value. But at that point you might as well just do a full DCF.
