Analysing trading scenarios using historical data

I shared my ideas about portfolio rebalancing and started testing out different scenarios using historical data. I've been working on some scripts to help me do some calculations, the scripts keep getting better allowing me to perform more tests. Maybe someday the scripts will be mature enough to share with others, but that is not yet the case.

For these tests, I used a dataset going from Jan 1st, 2017 until Nov 23th, 2017 for 4 cryptocurrencies: BTC, ETH, LTC and ZEC.
I assumed a starting budget of $2000.

Use Case 1: Even Distribution, Untouched

If we distribute our budget evenly over each coin (buy $500 worth of each coin or BTC 0.5008363968, ETH 61.1995104, LTC 110.864745, ZEC 10.31565917), this would be the result today:

In other words, if we had invested $2000 and didn't touch our portfolio until today, the value today would be $45,415 (22,707% increase).

Use Case 2: Weighted Distribution, Untouched

For this I used the following portfolio distribution:

• BTC 35%
• ETH 30%
• ZEC 25%
• LTC 10%

So let's start with the same budget of $2000 on January 1st 2017 and divide it using our distribution ratio (BTC 0.7011709555, ETH 73.43941248, LTC 44.34589, ZEC 10.31565917).

This would be the result today:

In other words, if we had invested $2000 using our portfolio distribution and didn't touch our portfolio until today, the value today would be $47,694 (23,847% increase)

Use Case 3: Weighted Distribution, Reinvested Profits

In this scenario, I tested what would happen if I would take the profit (if any) from the best performing coin that day and invest the profits into the lowest performing coin.
For example, if BTC would go up $50, I would sell $50 worth of BTC and buy more of the least performing coin (because this one got cheaper).

In other words, if we had invested $2000 using our portfolio distribution and reinvested the profits today, the value today would be $47,187.40.

Use Case 4 Weighted Distribution, Rebalanced Profits

In this scenario, I tested what would happen if I would take the change in distribution from the best performing coin that day and invest the profits into the lowest performing coin.
For example, if my value of BTC would go from 35% to 37%, I would sell 2% of my BTC and buy more of the least performing coin (because this one got cheaper).

In other words, if we had invested $2000 using our portfolio distribution and reinvested the profits today, the value today would be $43,089.53.

So far, there isn't much difference between even and weighed distribution and rebalancing didn't give much better results either.

I decided to have a look at what would have happened if we had put all of our $2000 on one cryptocurrency

Use Case 5: Everything on BTC

Buy $2000 worth of BTC on January 1st, 2017.

While this was still a good investment, the result is only $16,534.99 .

Use Case 6: Everything on ZEC

Buy $2000 worth of ZEC on January 1st, 2017.

While this was still a good investment, the result is only $14,291.73 .

Use Case 7: Everything on LTC

Buy $2000 worth of LTC on January 1st, 2017.

The result is for LTC is $34,576.50.

Use Case 8: Everything on ETH

Buy $2000 worth of ETH on January 1st, 2017.

The result is for ETH is $116,257.04. Now that is a nice profit!

Conclusion

First of all, I expected to see a bigger difference between weighed and even distribution of my portfolio. Also, portfolio rebalancing didn't seem to bring the results I had hoped for. Maybe my script isn't smart enough yet. Also, I only used one dataset, I should test over multiple timeframes and compare results.

Another thing you can see is that the 2 biggest winners are Litecoin and Ethereum while Bitcoin and ZCash are performing relatively less good. But if you read most articles and comments on SteemIt and Facebook, most people feel happy about BTC performance and complain about ETH and LTC.
IMHO, this is because they only look at absolute numbers instead of the percentage. And probably a lot are also late to the game and only look at the short-term gains.

I hope these calculations offered people some perspective. If possible I will keep improving my scripts to do more analysis and include more coins. Currently there is still a lot of manual work to import the data that I need to try and automise.
