When screening for stocks, I some times do a scattergram of the PE and PBV. I then look for those with both low values for both. There are about 20 odd Bursa companies under the packaging sector. The PE: PBV scattergram of them as of Sep 2023 is shown in the chart below. Note that I have excluded those whose PE < negative 20 for the purpose of this chart https://i.postimg.cc/90C1kzPw/Packaging-PE-PBV.png.
You can see that there are 2 companies as circled in red that have the lowest PE : PBV values. They are KYM and PPHB
Note that a cheap stock does not necessarily mean a good investment ie one that can enable you to make money. As a value investor, I use these in conjunction with some other fundamental metric eg ROE to narrow the screen.
In my ROE screens, I not only look at the historical ROE but also compare them to my reference – New Toyo and Canone – where I have detailed analysis. https://www.i4value.asia/2022/03/has-new-toyo-move-beyond-being-cigar.html#more
