It concerns weekly profits of some sort of managed forex account (what they say it is). In Excel I made a chart of their weekly yield (compounded weekly) over 26 weeks and added a (default) exponential trendline to it. This line becomes an excact straight line, (luckily slightly upwards). I have no excact knowlage of this, but is it a "natural" situation for an exponential trend to develop like this or should it be more curved?
I'm realy interested to know, because they could be a ponzi/pyramid scam with a sophisticated pre-setup profit system.

No it can never be.It can be possible or impossible.Even if the profit is gradually increasing it will still be a curve.

For a slow enough exponential growth, the trend might seem linear. If you fit the trend line to the data, then there is no way the exponent could be zero--that would yield an absolutely flat line, because anything raised to the zeroth power=1.

If you are sure you have an exponential trend, it can not be a straight line. It must increases faster as x increases, i.e., curves more than linear.
