Portfolio Contribution for Model Portfolios

Great update. However, kinda bummed that some of these features are only available with the highest (and recently added) Advisor Pro subscription. I had the highest subscription (which increased in price recently) and now Koyfin is adding higher subscription tiers. Feels a little bit like a bate and switch imo.

Conor MacNeil thanks Conor. There is an issue regarding short position in calculation. It appears like negative contribution while its suppose to be positive.

Yellow green Nightingale Hey Hicham, what rebalancing frequency do you have this model set to?
It's possible that this is influencing the contribution. If you have rebalanced during the month of June then it would depend on the dates you rebalanced.
For example, if you were 20% short QQQ and then rebalanced to 5%, the performance of the QQQ between those periods could result in you having negative contribution for the month despite the fact the fund itself is down MTD.
It should be working correctly. If you are 100% short QQQ in a model it would show a positive contribution in MTD due to the fact the fund is down 3.3%.

In addition to standard performance attribution, I’d like a metric that captures both the frequency and the magnitude of successful investments. Right now we can see a ‘hit rate’ or batting average (how often positions are winners), but what we’re missing is the investment equivalent of slugging percentage — something that weights each win by its impact (total contribution or excess return per position relative to risk).
Could you add a statistic that calculates:
Batting Average: % of investments/trades that outperform their benchmark.
Slugging %: Total contribution of winners ÷ number of opportunities (or ÷ all positions), weighted by magnitude.
This would allow us to evaluate not only how often we’re right, but how much being right actually matters.

Model Portfolios - Performance Attribution

When can we expect performance attribution to be included in the model portfolios analysis? This is a very important tool to help understand the ultimate performance and underperformance of different models. Thank you
Conor MacNeil
Hey Ian, we have explored contribution and attribution. There was some performance improvements we wanted to get through before we did that (these calculations are intensive on the system).
We plan to tackle contribution and attribution in the future, perhaps if you'd like to break down a few examples of your desired workflow, this will help us when we come to build it.

Conor MacNeil Hi Conor. Our firm has shown interest in Koyfin on a broader level as well. One of the key characteristics of other services that they appreciate is the ability to look into performance and see what funds or stocks are contributing to the total return. This would be key in helping us determine if active management choices have provided the alpha we may have been hoping for.
-Absolute contribution to return for each fund (how much each fund added or detracted from the total portfolio return).
-Relative contribution compared to our benchmark (if given).
I would imagine we can get there by multiplying the weighting of the holding by the return of the holding. If we sum the totals we would get the total portfolios return. Doing this over multiple time periods would be helpful for us in creating and sharing our narrative and broader themes with clients.
Today we aren't able to see what a certain holding did without going and looking up the holding separately when looking in models.
Conor MacNeil
Prospective Impala: This is great feedback, and aligns with what we are planning to do with respect to attribution. We will update this ticket as and when we move forward on that, and hopefully we can do it sometime soon for you.
