About this app

Why Stock does not predict whether the market will "go up" or "go down."

AI calmly explains, based on sourced evidence, why the market moved the way it did today.

■ Three times a day, via Card News

· Early Morning US Market Why — Why the US stock market moved overnight

· Korean Market Key Points — Things to watch before the market opens today

· Today's Review — What moved the market after the Korean market closes

Read the 9:16 Card News one page at a time, making it easy to read during your commute.

■ We do not predict

Key points are always presented conditionally and from multiple perspectives.

We go as far as stating, "If the flow is like this, this could happen."

We do not make definitive forecasts, nor do we tell you to buy or sell specific stocks.

■ We grade honestly — Honesty Index

We grade ourselves in the evening to see if the key points identified in the morning were actually correct.

If we are wrong, we do not hide it and explain "why we were wrong." This self-scoring record is the basis of the trust this app offers.

■ If there is no evidence, we say there isn't

We do not fabricate reasons on days when there is no clear material.

We honestly state, "It was a quiet night," or "It was an index-linked trend."

The actual sources for news, supply and demand, and indicators are displayed alongside every explanation.

■ Sectors of Interest

If you select a sector of interest, such as semiconductors, secondary batteries, automobiles, biotech, shipbuilding, or defense,

you can receive key points and reviews for that sector right on the home screen.

■ Archive

You can revisit cards from past days.

Search for "Why did it drop that day?" to retrace market trends.
We provide commentary and reasoning on why the market moved today through card news three times a day.
