Sell daily buy weekly?!

[Whycliffes]

I often notice that when a stock's (on a daily screen) ranking falls below the level that suggests it should be sold the following Monday, it starts to decline the week before the sell week.

My initial thought is to sell quickly and potentially wait until Monday to buy new stock.

However, when I've tested this strategy in a simulator (with daily rebalance, and WeekDay=x) , it hasn't led to significantly better returns.

Does anyone have experience to share using daily simulations for stock trading? Is it advisable to sell a stock immediately when its ranking falls and wait until the following Monday to buy a new one?

@Whycliffes

it starts to decline the week before the sell week.

The daily screen uses rankings based on the most recent fundamental data while daily rebalance in a simulation uses rankings based on fundamental data of the previous weekend.

You can vote here to change this:

Daily fundamentals for backtests and rebalances

Project Calculate factors daily instead of weekly for simulations, rebalances and factor list downloads. Also allow for intra-week rebalancing, for example on Tuesday, or daily rebalance for simulations and automatic rebalances.

Yes, that's right. Even if I run the simulation daily, it won't capture the most recent changes, or?

Is there a way to receive daily alerts when a stock crosses a specific score threshold, without manually running a screen?

The live strategy will allow you to capture the most recent changes.
The simulated strategy will not. Ranking only updates weekly on simulated strategies.

Very important feature (Simulations using the daily rank data not the weekly) ! Any update when this will go live?

I have noticed that If you do rankings via the API, that it changes on a daily basis. If you use the UI, it will only use weekly data
